挪威首都奥斯陆的北面,因供举行奥林匹克滑雪比赛而著名的城镇利勒哈梅尔正等待批准修建一处地下公路环形交叉,这将是世界上第一处地下公路环形交叉建筑。此方案是计划在地下修建4条3车道的隧道,在4条隧道的交汇中心修建一处直径为43m的大型地下公路环形交叉,在环形交叉的中心处需建一根直径为18m的巨型实心柱。这个方案将可缓和该城镇地面交通拥挤,特别是在举行冬季奥林匹克运动会期间交通拥挤更为严重。 To the north of Oslo, the capital of Norway, Lillehammer, a town well-known for hosting the Olympic skiing race, is awaiting approval to build a ring road intersection of underground roads, which will be the world’s first underground cross-ring road. Under the proposal, four 3-lane tunnels are planned to be constructed underground to construct a 43m-diameter underground ring road crossing at the crossings of the four tunnels. A giant solid 18m in diameter column. This program will ease traffic congestion on the ground in the town, especially as traffic congestion worsens during the Winter Olympics.
